Description

Kugelschraube Die Erfindung bezweckt eine Verbesserung der Kugelschraube nach Anspruch 1 des Patents 925 079. Diese Kugelschraube erfordert ein Rücklaufrohr für die Kugeln, das an der Ein- und Auslaufstelle der Kugeln eine Einfräsung erhalten muß, sollen die Kugeln geradlinig ohne Höhensprung von der Gewindeflanke in das Rohr einlaufen. Diese Lösungsform mit einem Kugelrücklaufrohr hat also eine Abweisernase, die aus dem Rohr selber gebildet ist und deren Stärke der Wandstärke des Rohres entspricht. Da die Rohrwandstärke im allgemeinen nur relativ dünn sein kann, ist die Abweisernase verschleißempfindlich.Ball screw The invention aims to improve the ball screw according to claim 1 of patent 925 079. This ball screw requires a return pipe for the balls, which are milled at the entry and exit point of the balls must, the balls should be straight from the thread flank into the Run in the pipe. This form of solution with a ball return pipe has a deflector nose, which is formed from the pipe itself and whose thickness is the wall thickness of the pipe is equivalent to. Since the pipe wall thickness can generally only be relatively thin the deflector nose is sensitive to wear.

Bei der aus der britischen Patentschrift 569 245 bekannten Kugelschraube ist das Rücklaufrohr in die Mutter gelegt. Die Kugeln werden hierbei durch eine feststehende Abweisernase rechtwinklig in das Rohr eingelenkt, was eine Behinderung des freien Laufes bewirkt.In the case of the ball screw known from British patent specification 569 245 the return pipe is placed in the nut. The balls are here by a Fixed deflector nose deflected into the pipe at right angles, which is an obstruction of free run causes.

Der vorliegende Erfindungsgegenstand schafft eine robuste Abweisernase, die sich spitz zwischen die Gewindeflanken schiebt und die Kugeln zwangläufig in einen tangentialen Auslauf zwingt, der sich im Rohr fortsetzt. Die Biegefestigkeit dieser schräg eingeführten Abweisernase ist natürlich erheblich höher als die Biegefestigkeit einer schmalen, aus einem Rohr gebildeten Zunge.The present subject matter of the invention creates a robust deflector nose, which pushes itself pointedly between the thread flanks and the balls inevitably into forces a tangential runout that continues in the pipe. The flexural strength this inclined deflector nose is of course considerably higher than the flexural strength a narrow tongue formed from a tube.

Die Abweisernase ist in einer besonderen Bohrung angeordnet, die gleichzeitig Einfüllöffnung für die Kugeln ist. Sie ist einstellbar und auswechselbar, ohne das Rücklaufrohr abnehmen zu müssen, und ist in der sie aufnehmenden Bohrung mit so viel Spiel angeordnet, daß sie in jeder Richtung federn kann.The deflector nose is arranged in a special hole that simultaneously Filling opening for the balls is. It is adjustable and interchangeable without that To have to remove return pipe, and is in the receiving hole with so arranged a lot of play that it can spring in any direction.

Der Vorteil einer solchen Abweisernase besteht in einer erhöhten Lebensdauer und in einer verminderten Störanfälligkeit.The advantage of such a deflector nose is that it has a longer service life and in a reduced susceptibility to failure.

Abb. 1 zeigt eine Ansicht der Kugelmutter, Abb. 2 ein Schnittbild der Kugelmutter quer zur Achse und Abb. 3 die Kugelmutter in Richtung der Achse.Fig. 1 shows a view of the ball nut, Fig. 2 shows a sectional view the ball nut across the axis and Fig. 3 the ball nut in the direction of the axis.

In Abb. 1 ist die Kugelmutter mit 1 und das Kugelrücklaufrohr mit 2 bezeichnet. Die Befestigung der federnden Abweisernasen erfolgt durch die Befestigungsschraube 3. Aus Abb. 2 und 3 ist zu ersehen, daß durch die federnden Abweisernasen 4 eine einwandfreie tangentiale Führung der Kugeln von dem Gewindeteil durch den Kugelkanal 5 in das Kugelrücklaufrohr 2 gewährleistet ist.In Fig. 1 the ball nut with 1 and the ball return pipe with 2 designated. The resilient deflector lugs are attached using the fastening screw 3. From Fig. 2 and 3 it can be seen that the resilient deflector lugs 4 a perfect tangential guidance of the balls from the threaded part through the ball channel 5 in the ball return pipe 2 is guaranteed.

Das Einfüllen der Kugeln erfolgt nach Herausnehmen einer der Kugelabweisernasen 4 durch die Bohrung für die Kugelabweisernase im Mutterkörper. An jeder Kugelmutter befindet sich eine Staufferfettbuchse 6.The balls are filled in after removing one of the ball deflector lugs 4 through the hole for the ball deflector nose in the nut body. On every ball nut there is a Stauffer grease bushing 6.
